Abstract

Provided is a device whereby it is possible to accurately recognize which area has been enlarged when part of an overhead image displayed on a monitor is displayed as enlarged. When any one area of a plurality divided areas (D1-D4) is indicated, the divided areas being a result of dividing an overhead image displayed on a monitor (21), an image of the indicated divided area (D1-D4) is set as an image to be enlarged, and an auxiliary display area (21B) is set as an enlarged display area. Enlarged display unit forms a plurality of intermediate images (M) of an intermediate size between the size of the indicated divided area (D2) and the size of the enlarged display area, and the intermediate images are sequentially displayed beginning with the smallest intermediate image (M), using the indicated divided area (D2) as an origin point.

Claims

1. A vehicle peripheral observation device, comprising:

a plurality of cameras for imaging an area including a road surface of a vehicle periphery;

a monitor, for displaying the images captured using the plurality of cameras; and

an image processor for processing the images for display on the monitor in the following manner; and

a primary display area on which an image captured by any one of the plurality of cameras is displayed and an overhead image display area on which an overhead image of the vehicle periphery is displayed when there is sensed a touch operation touching any area of the monitor while only one of the images is displayed in a display area of the monitor,

wherein the overhead image comprises a plurality of images captured using the plurality of cameras, and the overhead image display area is divided into a plurality of divided areas.

2. The vehicle peripheral observation device according to claim 1, wherein the image corresponding to the divided area which has been indicated in the overhead image display area as the image-to-be-enlarged is an image captured by at least one of the plurality of cameras.

3. The vehicle peripheral observation device according to claim 2, wherein the image captured by at least one of the plurality of cameras is an image including a viewpoint of the camera.

4. The vehicle peripheral observation device according to claim 1, wherein the image corresponding to the divided area which has been indicated in the overhead image display area as the image-to-be-enlarged is an overhead image of the vehicle periphery.

5. The vehicle peripheral observation device according to claim 4, wherein the overhead image of the vehicle periphery is an image including a viewpoint which is different from a viewpoint of the camera.

6. The vehicle peripheral observation device according to claim 1, wherein the image processor enlarges and displays, in the primary display area, at least part of the image corresponding to the divided area which has been indicated in the overhead image display area as the image-to-be-enlarged is enlarged.

7. The vehicle peripheral observation device according to claim 1, wherein the touching operation is performed on the image-to-be-enlarged.

8. The vehicle peripheral observation device according to claim 1,

wherein a frame in an outer periphery of the divided area indicated is emphasized.

9. The vehicle peripheral observation device according to claim 1, wherein information indicating which imaged area the enlarged, displayed image belongs to is superimposed on the enlarged, displayed image.

10. The vehicle peripheral observation device according to claim 1,

wherein an aspect ratios of the enlarged display area and the divided area are different from each other.

11. The vehicle peripheral observation device according to claim 1,

wherein the enlarged, displayed image includes at least a part of a vehicle icon and the at least a part of the vehicle icon is enlarged and displayed.

12. The vehicle peripheral observation device according to claim 1, wherein each of the plurality of divided images is a separate area of the overhead image that is capable of being selected by a touching operation.

13. The vehicle peripheral observation device according to claim 1,

wherein the image processor enlarges and displays, in the primary display area, an image corresponding to the divided area which has been indicated in the overhead image display area as an image-to-be-enlarged, and

the image corresponding to the divided area indicated in the overhead image display area as an image-to-be-enlarged is enlarged and displayed in the primary display area by a touching operation.

14. The vehicle peripheral observation device according to claim 1,

wherein the primary display area displays a camera icon showing the camera that captures the image displayed in the primary display area.
